The base of the transmitter has three ¾-inch NPT female conduit
openings, indicated in
Figure 4-1
, which must remain sealed to keep the
transmitter watertight.
• Use conduit that allows a complete seal with the conduit openings.
• If possible, orient the transmitter with its conduit openings pointed
downward. Seal the conduit to prevent condensation and other
moisture from entering the housing.
• To comply with requirements for explosion-proof installations approved
by UL or CSA, install approved explosion-proof conduit seals on all
three conduit openings.
• To comply with CENELEC requirements for installations in Europe, see
page 17.
